The eMac support is great for me, since its a affordable choice for me to try the OS out 
To bad it only supports the 1,25GHz revisions since a friend of mine could give me a 1,42 rev :/
Says who ? MorphOS does support these atleast by Apple's system-ID, so it will atleast boot.
MorphOS also supports Radeon9600s, just only as 2D.
So burn that CD, visit your friend and give it a try.....
